Title: Driving method of liquid crystal-optical shutter
Inventor: OOKUBO YUKITOSHI
IPC: B41J2/445
Filed: 1982-08-12
Abstract: PURPOSE:To enable high-speed response, by using the construction wherein upper electrodes for generating horizontal electric fields are made into a beltlike construction and lower electrodes for generating vertical electric fields are combined like a matrix and applying the vertical electric field in the rear part of every writing period. CONSTITUTION:Signal electrodes 101, 102 face to line electrodes 91, 92 through a liquid crystal. The signal electrodes are indicated by R and the line electrodes by C. The source voltage Vc of 501 is first applied to the electrode C1, and the electrode C2 is held grounded in this stage. The voltage applied state is made ON and the grounded state OFF. If the electrode C2 is OFF and the electrode R1 is OFF as well, there is no effect of an external field; therefore the liquid crystal is oriented to the initial wall bearing in a long standing time. In other words, the liquid crystal orients in a 45 deg. direction to the striped electrodes. Thereupon such pulse driving at which all the opening parts show a dark state is accomplished in the final writing period in order to avoid malfunction. The linear sequential time division system wherein the writing of the electrode C2 is carried out upon ending of the writing in the electrode C1 and the signal is inputted at one time to the common electrode is thus made usable.

Abstract: PURPOSE: To utilize the neutralizing ability of acidic gas with high eifficiency, while inhibiting its wasteful consumption, when alkaline waste water is neutralized with the acidic gas, by forming a by-pass channel in a flow pipe for the alkaline waste water mixed with the acidic gas.  
     CONSTITUTION: A casing 13 contains an alkaline waste water-neutralizing device and liquefied CO 2  bombs 7, 8 in it. Alkaline waste liquid, e.g. waste concrete liquid, is passed from an inflow opening 1a through a reversed U-shaped flow pipe 1, and discharged from an outlet 1b to a paddle mixer 5. Neutralizing CO 2  gas from the liquefied CO 2  bomb 7 is injected into the reversed U-shaped flow pipe 1 through a CO 2  gas-feed pipe 2 on the way of its upward flow part 1c, to neutralize the alkaline waste water. In this case, a by-pass pipe 3 is formed from the horizontal part 1d of the reversed U-shaped flow pipe 1, and a circulating channel is formed below the CO 2  gas-feed pipe 2, so as to accomplish sufficient neutralization with CO 2  gas. The feed amount of the CO 2  is properly controlled by a controller A involving pH detectors 4, 6 located on the way of a neutralized alkaline waste water channel.

Title: Image recorder
Inventor: OKI NAOYUKI
IPC: H04N1/387
Filed: 1988-06-09
Abstract: PURPOSE:To obtain a high quality image by exposing necessary information on one of plural surfaces of an original and erasing a latent image in a prescribed area at the time of exposing the other surface when the necessary information such as date is added to the prescribed area, at the time of multiple copying. CONSTITUTION:A shutter 70 is arranged on a photosensitive drum 20 so as to shield reflected light from an original. On the drum 20, an area shielded by the shutter 70 is exposed by a laser 91 as a second exposure means, and a character latent image such as predetermined date is formed. In multiple recording, an erasing lamp 70-1 as a third exposure means is not turned on when exposure is performed by the laser 91, whereas if the exposure is not performed, the lamp lights up and erase a prescribed character written area such as date on the drum 20. Thus, only one exposure suffices for writing the necessary information; therefore a high quality image is obtained.

Abstract: PURPOSE: To diagnose the progressing condition of osteoporosis by estimating the bone density and the modulus of elasticity of the bone. CONSTITUTION: A transducer 1 constituted by joining an ultrasonic delay spacer to the wave transmission, and reception surface of an ultrasonic vibrator transducer is pressed to organism and while this transmission and reception surface is oscillated and moved within a prescribed angle range toward the bone Mb, ultrasonic impulses Ai are intermittently shot and the surface echoes Ae1 from the skin surface and the bone echoes Ae2 from the bone surface are successively received. The CPU in an apparatus body 2 extracts the max. level from the received bone echoes Ae2 and thereafter, calculates the acoustic impedance of the bone Mb taking the attenuation rate of the ultrasonic waves into consideration in accordance with the max. bone echo level, the surface echo level making a pair therewith and the difference in the echo arrival time of this time.  The acoustic impedance of the bone Mb is expressed by the square root of the [modulus of elasticity × density] of the bone Mb. The modulus of elasticity (increases) decreases as well when the bone density increases (decreases) and, therefore, a good index in judging the bone density and the modulus of elasticity of the bone are obtd.
